We had the same question here at SCCWRP. Steve Bay is the scientist currently working on this question here at SCCWRP. I just recently gave him all of my gonad sections from my studies in the early 90's. Hi group is re-examining them for signs of sex changes. So, he would be a better person to ask, since I haven't looked at those sample for some 12 or 13 years now. His e-mail is steveb@sccwrp.org. Cheers, Larry

I'll try and write Steve soon but unfortunately have 0 time right now.
